How tankless electric water heaters work

Tankless electric water heaters, also known as on-demand water heaters or instant water heaters, operate by heating water directly as it flows through the unit without the need for a storage tank. When a hot water tap is opened (such as a faucet or shower), cold water from the main supply enters the tankless water heater unit. As the cold water flows over the heating elements, it gets rapidly heated. The heating process is controlled by the unit's computerised controls, which adjust the power output of the heating elements based on the desired water temperature set by the user. Since the water is heated as it passes through the unit, there's no need to wait for a storage tank to fill up and heat. This provides instant access to hot water as soon as the tap is turned on. When the hot water tap is turned off, the flow sensor detects the reduction in flow rate and signals the heating elements to shut off. This helps conserve energy by only heating water when needed.

Here are typical misconceptions about instant electric water heaters:

Misconception 1: Tankless water heaters are more expensive than traditional water heaters

One of the most common misconceptions is that tankless electric water heaters are always more expensive than traditional tank-based heaters. While it's true that the initial cost of a tankless unit can be higher, it's important to consider the long-term savings. Tankless units are designed to be energy-efficient, which can lead to substantial reductions in energy bills over time. Additionally, the durability and longevity of tankless units often outweigh their initial price difference.

Misconception 2: The water temperature delivery is inconsistent with tankless water heaters

Another misconception is that tankless electric water heaters deliver inconsistent water temperatures. The reality is that modern tankless units, even though they may be small, are equipped with advanced temperature control technology. These systems precisely regulate the water temperature, ensuring a steady and comfortable supply. When a hot water tap is opened, cold water flows through the unit's heat exchanger, which rapidly raises the water temperature to the desired level. The unit's temperature sensors and controls work in tandem to monitor and adjust the heat output, ensuring that the outgoing water maintains a steady temperature regardless of fluctuations in the incoming water's temperature or variations in water flow rates. This dynamic process of instantaneous heating and precise temperature regulation eliminates the risk of sudden temperature fluctuations, providing a reliable and comfortable hot water experience throughout the household or business premises.

Misconception 3: Tankless electric water heaters only supply limited hot water

Unlike traditional water heaters that rely on a limited storage tank, tankless units offer an endless supply of hot water on demand. This continuous flow ensures that your hot water needs are met without any interruptions, making it an ideal choice for households and businesses of all sizes. Whether it's early morning routines or evening relaxation, the consistent and reliable delivery of hot water from a tankless electric water heater redefines comfort and convenience in your daily life.

Misconception 4: Tankless electric water heaters have a short lifespan

The biggest point of failure within a regular water heater is the tank itself. During the heating process, minerals in the water separate, floating down into the bottom of your tank and clinging to heating elements. This causes sediment buildup, which can lead to a failure in the tank body. Once the tank ruptures, the entire water heater needs to be replaced. A tankless heater still contends with the corrosion caused by water, however, it doesn’t run the risk of a tank failure. With routine maintenance, a tankless unit can last up to twice as long as a standard tank water heater.

Misconception 5: Tankless electric water heaters use a lot of energy

These energy-efficient appliances address the inefficiencies of traditional tank-based water heaters by eliminating standby heat loss, which accounts for a significant portion of energy wastage. With tankless units, hot water is heated only when needed, putting an end to the constant energy consumption associated with maintaining a reservoir of hot water. Furthermore, the precision temperature control characteristic of tankless electric water heaters ensures that water is heated to the exact desired temperature, avoiding unnecessary energy expenditure.

Misconception 6: Safety is a concern with tankless water heaters

On the contrary, tankless water heaters completely eliminate the concern of tank leakage that often plagues traditional heaters plus most popular electric water heaters offer impressive safety features such as protection against dry heating, overheating, electric leakage and automatic malfunctions.

Misconception 7: Tankless water heaters take up too much space

Tankless water units are known for their space-saving design compared to traditional water heaters. They're compact and wall-mounted, which frees up valuable floor space in your home or business. This is especially beneficial for smaller living spaces where storage space is limited.

Misconception 8: All tankless water heaters are the same

With so many electric water heaters on the market today, it's tough to know which will best suit your water heating demands.
